Leading spaces are added to custom textarea metabox

[subrataemfluence]

I am using esc_atr(ltrim(rtrim(br2nl($meta_value)))) to place the value of post meta in textarea metabox I have created in my custom post type.

<textarea id="<?php echo $id_name; ?>"
   name="<?php echo $id_name; ?>"
   rows="7" cols="80"
   style="width:100%" maxlength="<?php echo $maxlength; ?>"
   placeholder="<?php echo $placeholder_text; ?>"
   <?php if($is_required){ ?>required<?php } ?>>
   <?php echo esc_attr(ltrim( rtrim( br2nl($input_value)) ) ); ?>
</textarea>

But whenever I go to edit the post, inside all textarea metaboxes values are pre-loaded with leading spaces (exactly 10 spaces) and additional line breaks!

Also tried esc_atr(trim(br2nl($meta_value))) with no avail.

I believe this is something related to core. I did not use any plugin to create the custom post type and it was done pure WP way.

You should remove new line or space between the <textarea> open tag and textarea content

<textarea>Hello world</textarea>

instead of

<textarea>
   Hello world
</textarea>
